During gameplay I started having this problem where the plunger sends a second ball into play at random times while I have a ball already in the playfield. It usually happens once or twice during the game while the active ball is moving and even happened once during destroy the ring last night. It does not appear to be a multi-ball issue.
The only areas of the game I have worked on recently are the flipper coil sleeves and the ring spinner switch, so I am wondering if I caused a problem in one of those areas.
Any suggestions would be greatly appreciated.
Thanks
